Dublin Airport's planned expansion to 60 million passengers per annum will do at least €8.4 billion worth of damage in global warming terms. This can de deduced using DAA and Ryanair data and new analysis contained in the Stern Report: "The Economics of Climate Change."

Ryanair has a rather new and relatively environmentally clean fleet that generates about 93 kg of carbon dioxide per passenger carried. According to Professor Stern this means each Ryanair passenger does about €17 damage in global warming terms. If we assume this rate of damage for all Dublin Airport passengers we are understating things because the Aer Lingus fleet is much older and their passengers travel, on average, 50% more kilometres. This means that Dublin Airport's 21 million passengers in 2006 did at least €357 million damage. When Dublin Airport expands to 60 million passengers a year around 2035 they will be doing over €1 billion global warming damage per year, every
year. The expansion alone will add some 40 million passengers doing €680 million damage every year. When we add up all the damage done between now and 2050, using discounting factors provided by Prof Stern, we get a total damage bill in today's terms of at least €8.4 billion.

This minimum total climate change cost of €8.4 billion is additional to the €4.5 billion net economic cost UPROAR has estimated for the proposed expansion plan of Dublin Airport. See: www.norunway.com/t2a/appt2.htm. That waste is due to a misuse of very valuable land, the economic cost of resulting road congestion and an estimate of the loss of welfare to communities surrounding Dublin Airport. It can therefore be concluded that the expansion plans of Dublin Airport will incur, at a conservative estimate, a colossal net loss of €13 billion.
